A box of goldfish food can feed 3 fish for 4 weeks. How long will the box last if there are 7 goldfish?
-----
time is directly related to # of boxes of food and indirectly related to # of fish
--------------------------
Equation:
t = k*b/f
----
Solve for "k" using "A box of goldfish food can feed 3 fish for 4 weeks".
4 = k*1/3
---
k = 12
------
Equation:
t = 12b/f
---
How long will the box last if there are 7 goldfish?
t = 12b/f
t = 12*1/7
time = 1.71 weeks
